Reproductive System Flashcards
What is the difference between sexual and asexual reproduction?
Asexual reproduction is when an organism reproduces by growing larger and then splitting in two.
Sexual reproduction is when two organisms come together to combine their different characteristics to produce offspring.
Asexual reproduction does not allow for changes; sexual allows for changes/adaptation
